Seda protocol node installation

To set up a validator node for the SEDA protocol, here’s a detailed guide to help you get started.

1. Install Prerequisites

Ensure you have the necessary dependencies:

  • Go (version 1.20+)
  • Build essentials like gcc, make, jq, etc.

Install Go:

wget https://golang.org/dl/go1.20.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.20.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin

2. Install SEDA

Clone the SEDA repository and build the binary:

git clone https://github.com/sedaprotocol/seda-core
cd seda-core
make install

Check if sedad is installed correctly:

sedad version

3. Initialize Node

Initialize your node by setting a moniker:

sedad init <your-moniker> --chain-id seda-testnet

4. Set Up Configuration

Download the configuration files and place them in the appropriate directory:

curl -s https://raw.githubusercontent.com/sedaprotocol/testnet/master/genesis.json > ~/.sedad/config/genesis.json
sed -i.bak 's/seeds = ""/seeds = "<seeds-from-github-page>"/' ~/.sedad/config/config.toml

5. Start Your Node

To start your node, use the following command:

sedad start

You can monitor your node’s synchronization status:

curl -s localhost:26657/status | jq .result.sync_info

6. Create a Validator

Once your node is fully synced (check catching_up: false), you can create a validator.

First, generate a validator key:

sedad keys add <validator-key>

Then, create the validator.json file with your validator information:

{
  "pubkey": "$(sedad tendermint show-validator)",
  "amount": "100000000000000aseda", 
  "moniker": "<your-moniker>",
  "identity": "<optional-identity>",
  "website": "<optional-website>",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}

Create your validator by submitting the transaction:

sedad tx staking create-validator --amount="100000000000000aseda" --pubkey=$(sedad tendermint show-validator) --moniker="<your-moniker>" --chain-id seda-testnet --from <validator-key> --fees 5000aseda

7. Configure for Upgrades (Optional)

For automatic upgrades using Cosmovisor, install it:

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest

Add Cosmovisor to your environment:

echo "export DAEMON_NAME=sedad" >> ~/.profile
echo "export DAEMON_HOME=$HOME/.sedad" >> ~/.profile
source ~/.profile

Now, initialize Cosmovisor:

cosmovisor init sedad

8. Advertise Your Validator

To find your validator operator address:

sedad keys show <validator-key> --bech val -a

This is the address others can use to delegate tokens to your validator.

For more information, check out the SEDA documentation.
